Völsunga saga

The Völsunga saga is a legendary saga, a late 13th-century poetic rendition in Old Norse of the origin and decline of the Völsung clan (including the story of Sigurd and Brynhild and the destruction of the Burgundians). It is one of the most famous legendary sagas and an example of a "heroic saga" that deals with Germanic heroic legend. The saga covers topics including the quarrel between Sigi and Skaði, a huge family tree of great kings and powerful conquerors, the quest led by Sigmund and Sinfjǫtli to save princess Signý from the evil king Siggeir, and, most famously, Sigurd killing the serpent/dragon Fáfnir and obtaining the cursed ring Andvaranaut that Fáfnir guarded.
